AUTOMATIC-FEED CAPPING-MACHINE.

Specification of Letters Patent.

Patented Nov. 24, 1908.

To all whom it may concern:

Be it known that I, Gnono Kmnnoaann, a

citizen of the United States, and a resident of the city of New York, inthe county of New York and State of New York, United States of America,have invented certain new and useful Improvements in Automatic- FeedCappin hlachines of 'which 'the following is a specification.

ping machine made according to my invention. Fig. 2 isa perspective viewof a bottle stopper or cap which I have invented and in conjunction withwhich the present invention may be used to advant-a c. Fig. 3 is a sideelevation of a portion 0 my improved apparatus showing a part of theautomatic feed mechanism which I have invented.

Fig. -i-is a plan view of the automatic feed mechanism. Fig. 5 is afront elevation of a portion of my machine showing a pair of collars andcams which I use to actuate a feed arm. Fig 6 is a sectional sideelevation of the feed mechanism. This view is similar to that shown inFig. 3, but in this case the parts are shown in different relativepositions. Fig. 7 is a plan view of the parts shown in Fig. 6, thesection being taken through the line 7''( in Fig. 6.

Like characters of reference designate corresponding parts in all of thefigures.

10 designates a standard or frame upon which the various parts of myapparatus are mounted. This frame comprises a base 11 in which a treadle12 is pivoted at 13. A tension spring 14 is attached to the frame and tothis treadle to raise and to normally maintain the treadle and itsconnected parts in their raised position.

15 designates a vertically slidable rod which is supported by the frame10 at 16 and also by the bracket 17 which is rigidly attached to theframe. The rod 15 is connected with the treadle 12 by means of a pitman18. A collar 15 is attached to the rod;

15 near its .upper end.

19 and 20 designate two arms which extend horizontally from the frame 10and which may be constructed, as shown, to be integralparts thereof.These two extending arms are arranged to slidably support areciprocating shaft 21v which is associated with the rod 15 by means ofa yoke 22 which fits loosely over the latter. The shaft 21 isaflixed tothe outer end of the yoke 22 at 23 and is normally maintained in araised position by means of a compression spring 24 which surrounds therod 15 and is placed between the lower portion of the yoke and the upperportion of the frame 10. The lower end of the shaft 21 is provided witha flange 25 which limits the upward movement of the shaft by strikingagainst the outer end of the extending arm 20. The outer edge of thisflange 25 is threaded and a collar 26 is attached thereto. This collaris provided at its lower end with an inwardlv projecting lip 27 l 30esignates a forming rin or die which is provided with internal surfaces31 which are arranged to engage with ortions of a bottle stopper or,cap. This orming ring may be made up of a plurality of sectors heldtogether and in horizontal alinement by means of springs 32, 32 whichare set into grooves in the external surfaces of the sectors. Thisforming ring is preferably of a vertical length somewhat less than thedistance between the bottom of the flange 25 and the top of theprojecting lip 27. As it is held in place between these parts it istherefore loosely held thereby, and a'pin 33in one of its sectors andextending intoa hole in the flange 25 may be provided to hold theforming ring from rotation.

The lower part of the shaft 21 is bored out' I for the reception of asecondary or compression shaft 34 which is vertically movable within theshaft 21 and extends down through the forming rin 30. A pin 35 fixed inthe compression shaft 3 passes through the vertical slots 21 in thesides of the shaft 21 and limits the downward movement of thecompression shaft 34 within the shaft 21. The compression spring 36 isplaced within the hollow portion of the shaft 21 above the compressionshaft 34 to press the latter outward. The compression shaft 34: may bemagnetized or a permanent ma et 37 may be inserted within its lower end4.0 is a bracket permanently afiixed to the frame 10 and extendingaroundthe rod .15

7 to a point directly in front of the latter,

where, at 41, it pivotally supports the inner member 42 of a swingingfeed arm thus providing means for the latter to move horizontally. Themember 42 is rigidly attached to the pivot 41 as is also an actuatinglever 43 which carries at its outer end an antifriction roller'44. Theouter member 45 of the feed arm is pivoted at 46 to its inner member 42.The outer end of this arm 45 forms a cap-earrying head 47 which may becut out as is shown at 47 for the rece tion of certain parts of the cap.A cam ever 48 extends downward from the rear portion of the arm 45, anda stop lug 49 for limiting the downward position of the arm 45 may bemade integral therewith and arranged to engage with the underside of theinner member 42; A spring 46 may be provided and arranged to press thecap-carrying head downward.

A collar 50 is affixed to the rod 15 at a point opposite the bracket 40and this collar is provided with a projecting cam surface 51 which isarranged to coact with the actuating lever 43. A spring 41 is arrangedto keep the antifriction roller 44 against this cam surface 51.

Directly below the collar 50 anothercoll'ar 52 is affixed to the shaft15 and this lower collar is provided with a projecting arm 53 which isarranged to engage with the arm 48 in the manner which will be pointedout later. 60 designates a bottle stopper which I have invented and forwhich Letters Patent Number 829,341 were issued to me August 21, 1906.This cap comprises a disk 61 of magnetic material such, for example, ascommercial tin plate, having a depending flange 62 below which are proeeting fingers 63, 63. A lining of compressi le material 64 such as gorkis placed against the disk Within the an e.

A chute may be attached to the frame 10 as at 71 and this chute may beinclined sufficiently to allow the caps 60, when placed within it eitherby hand or from a hopper, to slide down to its lower end. Grooves 72 areprovided in the surface of this chute for allowing clearance for thedepending fingers 68,63 of the caps. At the lower end of the chute anopening 7 3 is provided. An escapement lever 74 is pivoted at the sideof the chute near its lower end at 75, and its trip lever 7 6 isextended into the path of movement of apin 45 upon the feed arm 45.

A bottle stand 80 is supported in the outer end of the braeket17. Bymeans of a spindle'8l and an adjusting nut 82 the vertical height'ofthis bottle stand may be varied. 83 is a bottle having a bead orshoulder 84 about the upper portion of its neck. The stand 80 isprovided for the purpose of sup porting such a bottle under thecompression pha'ft 34 and in vertical alinement with the atter.

eoaere The operation of this device is as follows:

Vhen the apparatus is at rest the various parts assume positions such asare shown in Fig. l. The first movement of the treadle 12 will cause thevertical rod 15 and its associated parts to be depressed. The firsteffect of this operation Wlll. be to remove the projecting arm 53 awayfrom the depending portion 48 of the feed arm 45 and to allow the latterto drop down into the position in which it is-shown in Fig. 3. The nexteffect of the operation will be to cause the antifriction roller 44 toride up upon the cam surface 51 and to thus swing the feed armhorizontally about the pivot 41. This will cause the cap-carrying head47 at the end of the feed arm to be-moved into a position directlyunderthe opening 73 at the end of the chute 70. At the same time the pin 45striking against the trip lever 76 of the escapement will cause thelatter to be moved and to allow oneof the caps 60 to drop through theopening 73 into the cap-carrying head 47 'The downward movement of theshaft 15 just described will bring the collar 15 down to the upperportion of the yoke 22. While the parts arein the above positions anoperator may place the bottle 83 upon the bottle to be moved downwardagainst the action of the spring 24. A ea 60 has been placed upon thelower end 0 compression shaft 34 in a manner which will be pointed outlater. The downward movement of the reciprocating shaft 21 and thecompression shaft 34 will continue until the bottle cap is placed uponthe top of the bottle '83, and as the reciprocating shaft 21 iscontinued in its downward -movement the cap will be firmly pressed downupon the bottle under the action of the compression spring 36, thuscompressing the lining 64. It may be seen that although the movement ofthe compression shaft. is arrested by the cap coming in contact with thebottle the reciprocating shaft 21 and the other parts which areassociatedtherewith may continue their downward movement. This downwardmovement will cause the cam grooves 81 ofthe forming ring 30 to act uponthe depending fingers 68 of the bottle cap and to press them inward andunder the bead or shoulder 84 around the neck of the bottle. The bottlewill thus be sealed and the operator may hen allow the various parts toreturn to feet of the upward movement of the rod 15 will be to move theportion of the cam surface 51 which pressed against the cam lever 43 insuch a manner as to allow the spring 41 to return the cam lever 48 andthe feed arm 45 to their original positions in aline mentwith thecompression shaft 34 and in the position in which it is shown in Fig. 3.

As the rod 15 continues its upward movement the arm 53'will'come incontact with the depending arm 48 and push the latter outward, therebyraising the feed arm 45 and its cap-carrying head 47. One of the caps 60is now in this cap-carrying head and as'the latter is raised up against:the compression shaft 34., the cap will be brought in contact withthe'compression shaft, and because the latter is magnetized or isprovided with a permanent magnet 37, the cap will remain upon thecompression shaft during the subsequent parts of the operation whichhave already been described. L

The above operations may be repeated indefinitely and the caps appliedto bottles rapidly because the apparatus is provided with the meansabove described for automatically placing upon the end of thecompression shaft 34 one of the caps 60 during each cycle of operations.
